Research Interests:

We are interested in the application of NMR spectroscopy in the areas of polymer morphology, molecular dynamics, and diffusion. The materials we study include elastomers, fibers, photovoltaic materials, polyolefins, ionomers, artificial bones, fire-retardant polymers, etc. We also inquire how the nanoscale structural and dynamical behavior governs materials’ macroscopic properties such as those under extreme dynamic environments.
